Optical bonding

Perfect vision without compromise - thanks to optical bonding! By removing air gaps between the display and glass, we ensure unrivalled clarity and reduced reflections. Find out more about the different materials and techniques that are responsible for this impressive optical performance.

Optical bonding materials

LOCA OCR

LOCA / OCR

LOCA (Liquid Optically Clear Adhesive) is a liquid, optically transparent adhesive that we cure using UV light. This highly transparent adhesive is ideal for the precise bonding of rigid components such as TFT displays, touch sensors and cover glasses.

OCA

OCA

OCA (Optically Clear Adhesive) is a transparent adhesive coating that is used particularly in lamination processes. This adhesive is suitable for bonding flexible and rigid components and is often used for bonding FF sensors to cover glass.

Gel

Gel

Gel is a flexible adhesive film that is ideal for the optical bonding of rigid components such as TFT displays and cover glasses. Thanks to its high flexibility, the gel adapts ideally to the surfaces and provides an even, transparent bond.

Optical bonding processes

Dam & Fill

Dam & Fill

Dam & Fill is a precise process in which liquid adhesive is applied in a targeted manner to bond displays, touch and cover glasses. Curing takes place quickly and efficiently using UV light.

Lamination

Lamination

Lamination combines flexible and rigid components using roll lamination and an autoclave process. An OCA coating ensures a homogeneous and stable optical bond.

Hybrid Optical Bonding

Hybrid optical bonding

Hybrid optical bonding combines the advantages of LOCA and gel in a cost-efficient process. The slit coating process enables precise adhesive application, ideal for high-volume touch solutions.

E-Field

E-field

E-field is an innovative process for cost-effective touch solutions on a large scale. It uses an electric field to control the joining process of cover glass and displays. 

Advantages of optical bonding

Excellent readability

By applying an adhesive layer between the display and the cover glass, the air-filled gap is filled. This not only firmly bonds the components together, it also changes the light refraction behaviour. Optical bonding allows more light to be transmitted without loss, significantly improving the display's visualisation and readability. Even in particularly bright ambient light or in direct sunlight, content can be displayed clearly and with high contrast.

Readability of bonded displays

Robustness

With the help of our optical bonding processes, we can increase the robustness of our displays to such an extent that they can be operated precisely and error-free even under challenging environmental conditions. The fixed connection between the display and the touch unit reduces the sensitivity to mechanical impact and also prevents the ingress of contamination. Extreme temperatures, moisture and liquids, dust, vibrations or the possible effects of force can thus be countered in the best possible way.

Robustness of bonded displays

Prevention of condensation

The clouding or fogging of a display is often due to the penetration of moisture when used in strongly fluctuating temperature ranges. Optical bonding fills the area between the display and the touch unit with the adhesive. This prevents (air) moisture from entering the space between the glass and display and condensing on the surface.

Bonding prevents condensation

Outstanding legibility

Improved display of content - even in high light intensity.

Robustness

Increased resistance - even under difficult environmental conditions.

Prevention of condensation

Bonding prevents moisture from penetrating the display and causing it to fog up - even in the event of significant temperature fluctuations.
